Transparent LAN Service Over Cable
Transparent LAN Service over Cable This document describes the Transparent LAN Service (TLS) over Cable feature, which enhances existing Wide Area Network (WAN) support to provide more flexible Managed Access for multiple Internet service provider (ISP) support over a hybrid fiber-coaxial (HFC) cable network. This feature allows service providers to create a Layer 2 tunnel by mapping an upstream service identifier (SID) to an IEEE 802.1Q Virtual Local Area Network (VLAN).

In an industrial automation application that relies heavily Station 1 sends a message to on the health of the Ethernet network that attaches all the station 11 followed by Station 2 controllers and computers together, a concern exists about sending a message to Station 11. what would happen if the network fails? Since cable failure is These messages will traverse the the most likely mishap, cable redundancy is suggested by bridge from one LAN to the configuring the network in either a ring or by carrying parallel other.

XMOS for AVB Ethernet Based Networking for Audio/Video
Only a few years ago, computer networks were complex beasts tended by special acolytes and running on different standards. Today they have become commonplace in many homes and offices, simply plugged together using Ethernet technology. The same revolutionary change is coming for Audio/Video (AV) networking, as AVB (Audio XMOS for AVB: Video Bridging) products that run over the same network, Ethernet based networking begin to enter the market. for Audio/Video Putting together networks of AV equipment for professional and consumer use, or for use in How Ethernet Works vehicles, is about to become simpler while also Within Ethernet, data is transmitted between delivering better quality. No longer will devices (such as a computer and a printer) in specialist connectors and cables be needed to packets. Each packet carries one or more create a rats' nest of connectivity. Instead addresses for its destination. Like a postal packet traversing the postal system, the network has no Audio Video Bridging (AVB), a set of knowledge of what is in the packet, but uses the international standards, will make setting up address to pass the packet to the next point in the and managing networks almost as simple as network. just plugging together the different elements.

Schedulability Analysis of Ethernet Audio Video Bridging Networks with Scheduled Traffic Support
Real-Time Syst DOI 10.1007/s11241-017-9268-5 Schedulability analysis of Ethernet Audio Video Bridging networks with scheduled traffic support Mohammad Ashjaei1 · Gaetano Patti2 · Moris Behnam1 · Thomas Nolte1 · Giuliana Alderisi2 · LuciaLoBello2 © The Author(s) 2017. This article is published with open access at Springerlink.com Abstract The IEEE Audio Video Bridging (AVB)technology is nowadays under con- sideration in several automation domains, such as, automotive, avionics, and industrial communications. AVB offers several benefits, such as open specifications, the exis- tence of multiple providers of electronic components, and the real-time support, as AVB provides bounded latency to real-time traffic classes. In addition to the above men- tioned properties, in the automotive domain, comparing with the existing in-vehicle networks, AVB offers significant advantages in terms of high bandwidth, signifi- cant reduction of cabling costs, thickness and weight, while meeting the challenging EMC/EMI requirements. Recently, an improvement of the AVB protocol, called the AVB ST, was proposed in the literature, which allows for supporting scheduled traffic, i.e., a class of time-sensitive traffic that requires time-driven transmission and low latency. In this paper, we present a schedulability analysis for the real-time traffic crossing through the AVB ST network. In addition, we formally prove that, if the bandwidth in the network is allocated according to the AVB standard, the schedula- bility test based on response time analysis will fail for most cases even if, in reality, these cases are schedulable. In order to provide guarantees based on analysis test a bandwidth over-reservation is required. -
